[center][/center]I'm happy to read that you found [url=http://www.bladerunner2-movie.com/community/forums/topic/395]my post interesting[/url]. =D
Why the empathy test (sure-fire way to ID them)? Empathy is something they clearly lack (supposedly in all cases). They aren't given the opportunity to learn/develop it, nor is it something somehow embedded by technological means. An ability they aren't given either-way, & likely on purpose. The idea that they weren't redirected with care; still would likely be, from some-type of policy that they aren't human, & so don't direct them as such. An intentional policy of non-redirection (without care). However, with what I believe your issue is, I do agree it is a possibility that empathy cannot be simply pre-programmed, among other. And must be learned over a period of time, just maybe it finally is ...during the course of the film (by certain replicant characters). Did Roy empathize with Deckard (motive for stopping him from the fall)? Or was it just he didn't want to be alone when he died (afraid of the dark, like a dying child without God)?
Maybe another reason they are given a limited-lifespan (also possibly restricted to only controlled-contact situations with humans) ...they might develop the ability to empathize, if given enough time, & experience (particularly on Earth when witnessing/or in extreme-hardship situations with others that can, for example). I believe that would make them much more difficult to control; especially, if they were designated for nasty-business. I'm sure empathy would have been something someone like Hitler would have liked to have had completely eradicated, from his Nazi killing-machine. And the replicant obsessions Tyrell speaks of in the film, might be the obsession (or virtue) to become more humane, ultimately human. A terrible obsession, that may require the retirement of the detuned replicant in question? Or the crime of wanting more, than Tyrell is willing (or morally-capable, or technologically) in granting?
The child-like behavior is something Rutger Hauer brought to his role, I believe. And Daryl Hannah followed suit, because they were like 'two-peas in-a-pod' on/off-set (Rutger basically was her mentor on the film). I believe the idea was that he (or the Nexus-6) hadn't had enough time with their 4-year lifespan to develop an adult-like/balanced mentally. I think it works, & makes Rutger's character more interesting. Also done with the blessing of Ridley; however, it also does borderline on a psychopathic line of conversation, too. So there is a duality to that as well, demonstrated in the scene with Chew. Leon is an idiot, also a brute, & Zhora seems just like a regular run-of-the-mill stripper, in conversation. And then we have Roy, & Pris baby-talking with each other in toy-land (I wouldn't be surprised if that continued off-set, with those two), also J.F, which is almost seemingly required when speaking to him, LOL. So yes, Roy, Pris, Leon, even J.F; we see child-like behavior. And with Zhora ...didn't see it. Something Rutger did, whether or not there was a clear-consensus on that; during filming, among the Nexus-6 actors/actresses is not known (another super question to ask of Ridley). Although, we can count Daryl in on that (likely Brion, too). Who knows, maybe J.F. is also responsible for that child-like behavior? I found it's somewhat vaguely implied, that he has something to do with what's in their head.
I like to believe the replicant motive is more complex than simply 'not fair'; although, still a valid portion/genesis of their gripe. Maybe it all ties back to why Phillp K. Dick wrote the original story BR was based-on, & where the concept initially came from (a non-human, human-being ... the screams of children keep me awake at night)? A fun question to ask is ...who in the film would you give that line to? And who are the (or their) children? I don't figure it was by accident that the replicants happen to lack empathy, but that is simply my own opinion. There is some intent there, to prevent the replicants from having (or developing) empathy ...certainly the test is one indicator of that, at least to me it is. Then again, much has been left so ambiguous that ...it's anyone's guess; useless we get something from the boss. Interruption of the film(s), is something that usually evolves overtime, & it has many times for me over the years. And of course, what makes the film(s) so much fun to be a fan of. Ridley has made a Private Dick outta us all, to some degree, LOL.
